punning the pcb to an array of ints and using magic indices to
access values in it. This should prevent silent breakage from
changes in the pcb.
Supply 0 for unavailable registers instead of punning the tss to
an array of ints and using magic indices to access garbage values
in it. (The registers are in the pcb; there is nothing interesting
in the tss. This should change someday. At least for dumps, all
the registers should be saved, and common_tss is a good place to
put them.)
Removed ancient wrong (disabled) method for reading eip.
UPAGES layout.. it was entirely too comfortable with reading and writing
the U area before. I've changed it to use PT_GETREGS/PT_PUTREGS
ptrace ops instead of READ_U etc. The code to read the registers from
core dumps is a bandaid at best. It seems to have problems reading
core dumps from dynamic linked executables still, but at least static
dumps work.
I desperately need help from a gdb/bfd expert. :-) HELP!!
"%%" in format strings and tends to dump core for "%%st". I needed
"%%st" to fix the new gdb ...
Don't use the private version of strerror() either.
Use INTERNALLIB and INTERNALSTATICLIB instead of a private install
rules NOPROFILE and NOPIC. This is only slightly cleaner.
INTERNALLIB was previously only used in compatibility libraries
(libgnumalloc etc.) and INTERNALSTATICLIB was previously unused.
INTERNAL*LIB probably should be replaced by something like NOSTATICO
together with NO{STATICO,PROFILE,PIC}INSTALL.
by the -DNO_MMALLOC flag in gdb/Makefile.
The one thing we lose by doing this, AFAIK, is the possibility of using
mmap. Does anyone use that feature at all ?
2.2 candidate ?
files using the texi sources in /usr/src/contrib/gdb/gdb/doc.
I put a pointer to /usr/src/contrib/libreadline/doc into
Makefile.inc in the hope that the appropriate files would be
picked up.
This is based on /usr/ports/devel/gdb.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
1) add Garrett Wollman's trap frame resolving mods
2) make the `proc' command (kernel debugging) really work
3) allow use of a pid with the `proc' command (previously you had to
provide the address of the proc structure)
Unfortunately, the `proc' command won't work while doing remote debugging.
alias `pcb_cr3' instead. That is still one alias too many, but is convenient
for me since I've replaced the tss in the pcb by a few scalar variables in
the pcb.

how embarassing ! This turns out to be a bug in infptrace.c. Below
is a patch. Could some kind soul apply it ?

of the linker to enforce linking of modules in command line order it is
not possible to link gdb shared with -lcompat.
*HACK ALERT*
Removed -lcompat from LDADD and bring in the necessary functions out of
libcompat as a source module until the linker can be fixed.
